+    {
+        // multiplication can overflow; go through safeint
+        if (FAILED(SIZETMult(items, size, &cbRequested))) { return NULL; }
+    }


The overflow check logic is incorrect. The condition sizeof(items) + sizeof(size) <= sizeof(cbRequested) doesn't actually check if the multiplication items * size can overflow. This should check if the total bit width of the operands is less than the result type, but the current logic is flawed. Consider using a proper overflow detection method or always use the safe multiplication path.

Suggested change

}

if (FAILED(SIZETMult(items, size, &cbRequested))) { return NULL; }

+        if (FAILED(SIZETMult(items, size, &cbRequested))) { return NULL; }
+    }
+
+    return HeapAlloc(GetZlibHeap(), 0, cbRequested);


The function is named z_custom_calloc but only performs allocation without zero-initialization. The calloc function should zero-initialize the allocated memory. Use HEAP_ZERO_MEMORY flag in HeapAlloc to ensure proper zero-initialization.

Suggested change

return HeapAlloc(GetZlibHeap(), 0, cbRequested);

return HeapAlloc(GetZlibHeap(), HEAP_ZERO_MEMORY, cbRequested);
